BC Racing has built its reputation by producing suspension systems for a wide range of road, modified and competition vehicles. Rather than relying on one universal specification, the company develops its kits around individual vehicle platforms. Vehicle weight, suspension geometry, available travel and intended use are considered when selecting the initial spring and damper setup.

This development process gives drivers a practical starting specification while retaining the adjustment needed to personalise the vehicle. BC Racing kits are commonly used for everyday road cars, fast-road builds, show vehicles and track projects.

Vehicle-Specific Configuration

The features supplied will depend on the selected series and vehicle application. Available configurations can include damping adjustment, ride height adjustment, monotube dampers, replacement top mounts, pillowball mounts and camber adjustment.

The kit includes suspension units for all four corners. Depending on the application, original top mounts or rear springs may need to be retained. Always review the selected variation before ordering, especially where several suspension layouts are available for the same model.

Installation and Final Setup

The original suspension must be removed before the coilover components are installed and adjusted. Certain vehicles may require additional work, including modification of the original suspension components or a weld-on mounting arrangement. Any welding must be completed by a qualified professional.

A wheel alignment should follow installation and any significant ride height adjustment. Available from Paramount Performance, vehicle tuning and performance specialists since 1986.
